Improvements in Tools for Molding Cornices, of which the following is aspecification.

This invention relates to tools for molding cornices, whereby cornersmay be turned and the cornice entirely completed with one and the sametool.

In the accompanying drawings, Figures 1 and 2 and 3 are respectivelyplan and rear side views of a tool constructed in accordance with ourinvention. Fig. 4 is a section on line 7 7 of Fig. 2.

Like numerals designate similar parts throughout the several views.

Frequently it is necessary to'change the angles of the sides of thetoolin other words, to adjust said sides so that the said tool may bemade to accommodate itself to wall-surfaces and moldings of any sort-andto permit this to be accomplished various means may be employed and oneof which will now be described.

Referring to Figs. 1 to 4, inclusive, the numeral 12 designates a stripfrom which rises a plate 13, to the inclined upper edge of which issecured, by screws 14, one of a series of interchangeable die-plates 15,each of which may have an edge design of any required contour to bereproduced on the molding. Pivoted at 16 to the inner end of the strip12 are two arms 17 18 and to said arms are either respectivelyv securedor formed integral therewith curved plates 19 and 20, the plate 19having rack-teeth 21 and the plate 20 rack-teeth 22. Mounted for rotarymovement in the end of strip 12 is a shaft 23, having a threaded section23, said shaft being provided with a knurled finger-grasp 24, by whichit may be manipulated. Rigid with the shaft 23 is a inion 25, and saidpinion is in mesh with eac of the racks 21 22, so that when the shaft 23is turned the said racks and the arms 17 and 18 may be moved in or outto adjust the arms 17 and 18 in the manner described. A collar 26 ispinned to the shaft 23 just above the pinion 25, and said we claim iscollar and a head 27 of the shaft are supported in bearings of the wallsof a chamber 28 in the end of the strip 12 and through which the rackends of the arms 19 and 20 pass.

To look the parts just described against movement after an adjustmenthas been made, a knurled and chambered ja1n-nut 29 is threaded upon thesection 23 of shaft 23,

as illustrated more particularly in Fig. 4.

To change the angular position of the side bars 17 and 18, the nut 29 isloosened, and the shaft 23 is turned to cause the pinion 25 thereof toengage the rack-teeth on the side bars, and thus to adjust the same, andafter the desired adjustment has been made the nut is again tightened tolock said side bars rigidly in position.

Changes may be madein the various details of the invention withoutdeparture therefrom.

Having thus described our invention, what 1. A cornice-molding tool,comprising a support, sidebars pivoted to said support, overlap ing armsprojecting from said bars and eac having a rack; a pinion journaled inthe support; and a molding-die projecting from said support.

2. A cornice-molding tool comprising a support; a molding-die projectingfrom said support; side bars pivoted to the support; racks rigid withthe side bars and projecting laterally from said side bars; a pinionengaging said racks; and means for locking said pinion.

3. The combination, with a pair of pivoted side bars, of a supportconnected to said side bars; a molding-die carried by said sup ort armsprojecting from the outer ends 0 the side bars and each having a rack ashaft j ournaled in the support; a pinion carried by said shaft and inengagement with the racks; means whereby the shaft may be rotated; acollar on the shaft; and a chambered jamnut threaded upon the shaftadjacent to said collar.

In testimony whereof we aflix our signatures in presence of twoWitnesses.
